This invention relates to improvements in road markers particularly adapted, though not necessarily limited in its use, in connecttion with pedestrian-and vehicle traffic, and

.3 one of the objects of the invention is to provide an improved marker of this character adapted. to be embedded in the pavement and an improved method of preparing the pavement for the reception of and placing of the la marker in position.

`A furtherl Objectis to provide improved means for anchoring or securing the marker in position in the pavement and in a manner to prevent accidental or unauthorized rei8 moval of the same.

1 A further object is to provide an improved marker of this character which may be readily placed in position in a pavement which has alreadybeen constructed or laid in a pavement which is under course of construction,

the upper surface ofthe marker when in position being substantially flush with the adjaf cent surface of the pavement. Y

A further object is to provide improved means for forming in the pavement a poclet or reces-s adapted to receive the substance constituting the marker proper and which recess or pocket will be of a contour or configuration in simulation of the` character or object to be depicted by the marker.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompan-ying drawings illustrating this invention,

and in which A Figure 1 is a vertical, longitudinal sectional view taken on line 1-1, Figure 2.

Figure" 14 is a sectional view taken on line 'lll-141, Figure 13.-

Referring more particularly to the drawings the numeral 15 designates a form., which in the present exemplification of this invention, is in the shape of a letter or character which will constitute a portion of the marker.4

This formlmay be constructed of any suitable material preferably metal and may be of any desired size and configuration.

The form is preferably hollow and thelow er edges of the wall or wallsfthereof are cut away as at 167 any number of'wh'ich cut away portions may be employed.

The numeral 17 designates generally an anchor member whichmay be constructed of any suitable material, but is preferably of some rigid material such as metal and may be either shaped in the form of a fla-t member with the extremities 18 thereof deflected yor 9'5" the anchor may becast or molded.

These anchors may be of any desired size and length and are adapted'to enter the openings 16 in the form 15 when the latter'y is placed in position in thepavement, and the V100 perspective View of i any suitable material of a plastic, semi-plastic anchor members 17 project for any desired distance beyond the sides of the form.

In placing the marker in position the anchor members 17 are placed upon a road bed 19 and in such position that when the form is placed upon the road bed as shown in Figure 8, the openings or cut away portions 16 will receive the anchors 17. The number of anchors 17k which are employed depends upon the form or shape of the character and the extent that it is desired to'anchor the marker element. e Y A After the parts have been assembled'as shown in Figure 8, the pavement 2O is placed in position so that it will contact with the sides of the form 15, the extremities of the markers 17 and deflected portions 18 thereof being embedded in the pavement.

A portion of the pavement 2O may pass through the openings 16 in the form but this will not be objectionable.

After the pavement has been allowed to stand for a suliicient length of time so as to allow it to set or partially set, the form 15 may be removed as shown in Figure 10, but

the anchor element 17 will remain in position so that when the form 15 has beenremoved there will be provided in the pavement20 a. pocket or recess 21 opening through the top of the vpavement and in the form of the character or letter delineated by the form 15. It will be noted that the anchor element 17 will always be spaced above the bottom of the pavement or above the road bed 19.

It will be manifest that with this invention any form or character of marker may be provided, that is to say the marker will be in the form of a single element or separate elements arranged together to produce a word or assembled characters.

As shown in Figure 12, the word Stop has been outlined by the pockets or'recesses in the pavement 20.

The'marker element proper 22 is formed of or pulverulent nature which will be VV of a consistency thatit maybe placed within the pockets or recesses 21 so as to fill the pockets or recesses, some of the material passing. f under the portion of the anchor 17 that passes transversely through thepockets or recesses above the bottoms thereof.

' The material of which the marker elements proper are formed is suoli that it will withstand'considerable wear and when placed in position will be anchored in such a Vmanner thatit will not be readily displaced.

If' desired, any suitable material 23 such-as cement or the like may be interposed between the wall of the marker element proper and the adjacent wall of the pocket or recess containing the element so as to seal the same against the possibility of the entrance of any moisture into the pockets or recesses.

The pockets or recesses 21 may be formed of any desired depth and this improved marker is readily adapted to be inserted in a pavement which has already been constructed as well as in a pavement which is under the course of construction.

In the event that the marker is to be inserted in a pavement which has already been constructed, the portion of the pavement to receive the marker will be cut away to form an openingtherein large enough to receive the forni or forms and thel marker may be constructed in a single form or a plurality of forms adapted to be assembled' in any desired manner.

While it is preferable to employ a removable forin such as l5, for the purpose of forming the pockets or recesses, it is to be understood that the present invention is not to be limited to a removable form as the form itself may constitute the pocket or recess. Such a form is shown in Figure 13, in which the material constituting the marker element proper will be deposited or placed within the form itself. If this form is to be allowed to remain in the pavement the anchor elements may be formed integral withv the form, so as to project into and across the form as well as project beyond the lateral walls of the form.

In this form of the invention the numeral 2e designates the form and 25 anchorportions formed integral therewith and projecting beyond the outer face of the form. Similar anchor portions 26 are also formed integral with the form and project into and in a direction across the form. The anchors 25 will be embedded in the pavement while the anchors 26 will be embedded in the body portion of the member proper.

W'hile the preferred forms of the invention and the preferred method of placing the marker in position in the pavement have been herein disclosed, it is to be understood that various changes may be made in both, within the scope of the claims, without departing from the spirit of this invention.

l/Vhat is claimed as new is 2- 1. The method of placing a road marker which consists in placing in a pavement an anchor, then placing a form in the pavement over the anchor, a portion of the anchor extending beyond the form, then filling in the pavement around the said form and over .the

projecting portion of the anchor, then removing the said form to provide a recess or pocket, the said anchor remaining in theV pavement and extending in a direction across the recess or pocket, and then filling in the recess or pocket with a suitable material to form the body of the marker, theportion of the anchor in the saidv recess or pocket being embedded in the body of the marker element.

2. The method of placing a r-oad marker which consists in placingv in a pavement an anchor, then placing a form in the pavement over the anchor, the said form having one or more recesses opening through the bottom thereof to receive the anchor, a portion of the anchor extending beyond the form, then filling in the pavement around the said form and over the projecting portion of the anchor, then removing the said form to provide a recess -or pocket, the said anchor remaining in he pavement and extending in a direction across the recess or pocket, and then fillingl in the recess or pocket with a suitable material to form the body of the marker, the portion of the anchor Vin the said recess or pocket being embedded in the body of the marker element.

3. The method of placing road markers in pavements which consists in placing in a pavement a form and anchoring means extending across and disposed below the top of said form, a portion of said anchoring means projecting beyond the lateral faces of the form, said form serving to provide a pocket or recess in the pavement of substantially the shape of the marker, and then filling in the said pocket or recess with a suitable material to form the body of the marker and embed the portion of the said anchoring means which is within the form.

4. The method of placing road markers in pavements which consists in forming an opening in the pavement, then placing a hollow form in the said opening, said form being of a size to form a space between its. periphery and the wall ofthe opening, then filling in the space between the periphery of the marker element and the adjacent wall o-r face of the pavement with a cement, then removing the form to provide a pocket or recess in the pavement of substantially the shape of the marker, then filling in the said pocket or recess with a suitable material to form the body of the marker element.

5. The method of placing a road marker in a pavement which consists in forming in the pavement a pocket or recess of substantially the shape of the marker element, then placing an anchor element in the recess to extend in a direction thereacross and spaced above the bottom of the recess, and then lling in the recess with a suitable material, the anchor element being embedded in and extending beyond the upright face of the marker element. l 6. A road marker directly shaped and constructed in a pavement while the latter is be# ing made, said marker embodying a body por-- tion constructed of paving material, the upper surface of the marker being substantially iiush with the adjacent surface of the pavement, and an ancho-r embedded in the body of the marker element, a. portion of the anchor projecting beyond the lateral edge of the marker element intermediate the upper and lower faces of the element, to be embedded in the pavement and in the marker during the operation of constructing the marker in the pavement.

7. A road marker embodying a block like body portion, an anchor element embedded in the said body portion intermediate the top and bottom surfaces thereof and spaced from both, the ends of the anchor projecting beyond the edges of the body, said projecting ends extending downwardly, the extremities of said downwardly extending portions beyond the said body being substantially flush with the lower face of said body portion.

In testimony whereof Il have signed my name to this specification on this 11th day of January, A. D. 1927.
